Sharing variables between functions

[sharmilah]

Hi all

It's me again.. I have a variable to which i am assigning a value in one function. I have to use the variable with the same value assigned in another function. How can I do this. I've tried to portray this in the following codes

Thanks.


[PHP]Function x
{
$a =25
}

Function y
{
If ($a=25)
sql_insert();
}[/PHP]

[CODE=php]
<?php
function FuncOne(){
$toFuncTwo = 25; // CHANGE THIS
return $toFuncTwo;
}

function FuncTwo($Return edValuefromFunc One){
if($ReturnedVal uefromFuncOne== 25)
{
$Msg = 'True';
}else
{
$Msg = 'False';
}
return $Msg;
}
$returnValue =FuncOne();
print FuncTwo($return Value);
?>
[/CODE]

you could also make a "global" variable

[PHP] $var = '';

function funcOne()
{
$var = 25;
}

function funcTwo()
{
echo $var;
}

echo $var; //outputs an empty string
funcOne();
funcTwo(); //outputs 25
[/PHP]
but i like ajaxrands solution more, since one rarely want to use global variables unless unavoidable :)
